Kubuntu 16.04 on Lenovo P50

I have been running openSUSE for years.

When I got the Lenovo P50 laptop with a HiDPI screen I was not able to get the Nvidia proprietary driver to run with the resolution I wanted.

It turns out that there is more to HiDPI than just the driver. And the fact that I have an external monitor that is not HiDPI probably makes it even harder.

Nevertheless I have colleagues who were able to get the same hardware to work with the proprietary Nvidia driver. They were running Linux Mint Cinnamon Edition. I'm not sure which version actually.

I ended up trying out Kubuntu to figure out if that would help. It did not. I got the exact same issue as I had with openSUSE.
But not only that. I had issues with things that worked in openSUSE Leap 42.2. Sound wouldn't always play through headphones. The only workaround I have found is to restart the OS.
My music streaming service that is based on the browser sometimes don't play any songs when I click play. The browser I use is Google Chrome but the web application is not as stable as in the same browser in openSUSE.
Adding the smb based network printer at work is not possible through the printer configuration interface. YaST on openSUSE was able to do this.

I am considering multiple things to do from here:

1. Go back to openSUSE Leap (maybe wait until 42.3 at the end of July)
2. Try Linux Mints KDE version.

On top of that it would probably also help if I got a HiDPI monitor to connect to my laptop.

The Wayland display server protocol should also be much better at handling the combination of HiDPI and non-HiDPI monitors. It does not seem like Wayland is ready for primetime yet though. Fedora has Wayland as default display server. So that could be a possibility.
